e2v has added the 2MP EV76C570 device to its Sapphire family of industrial CMOS sensors. A 1/1.8-inch sensor is based on 4.5um pixels. An extra effort has been spent to make it compatible with older 1.3MP sensors in Sapphire family, including the pinout, package, optical format and register banks retained to minimize customer efforts to adapt the new 2MP product.

The new sensor features:

Both rolling and global shutter configuration with high global shutter efficiency

Up to 60fps frame rate

4 x separately configurable regions of interest including the possibility to programme each window with separate exposure and gain settings

A histogram embedded in the footer of the image data field for image statistics to reduce the processing overhead for auto exposure/gain algorithms

A lin/log pixel response mode for high dynamic range image capture

A 10 Bit parallel output which can be compressed to 8 bits using a multi-slope companding technique.

Formerly known by its CCDs, Truesense Imaging re-enters CMOS image sensor market with the new 12MP 4/3-inch KAC-12040 based on 4.7um 5T global shutter pixel. The new sensor is delivers 60fps at full resolution of 100fps in 4K 8.3MP 16:9 mode. The fast output is delivered through 64 LVDS lanes in 260MHz DDR manner. The ADC resolution can be selected in 10b to 14b range. The power consumption is 2W in 12MP/60fps mode.

The pixel full well is 13Ke-. The read noise is 10e in rolling shutter mode and 30e with global shutter, meaning DR of 62dB with rolling shutter or 52dB with the global one. The reported QE for Bayer color version is 40%, 45%, 43% at 470, 540, 620 nm respectively. The monochrome version's QE is 50%, 18%, 11% at 500, 850, 900 nm respectively.

The KAC-12040 Image Sensor is available in monochrome and Bayer color configurations, and is sampling now with production planned for Q2, 2013. An evaluation system that allows detailed analysis of the sensor’s performance is expected to be available in Q4, 2012.

The KAC-12040 CMOS sensor is said to be the first in a planned family of CMOS devices that complement Truesense Imaging’s CCD portfolio by providing the functionality and flexibility available uniquely from CMOS technology.

PR Newswire: OmniVision announces the OV8835, a 8MP 1.4um pixel sensor for smartphones and tablets, an improved version of similarly speced OV8830. The 1/3.2-inch OV8835 is built on a newly improved 1.4um OmniBSI-2 pixel that delivers dramatically improved sensitivity of 1000 mV/(Lux-sec), a 20% improvement over the previous-generation OV8830 (however, the product brief doc gives 824mV/(Lux-sec), same as the older OV8830). Other performance improvements over the OV8830 include a 20% improvement in low-light performance and a 25% improvement in full-well capacity. (Note that the older OV8830 was said to deliver 20% improvement in peak QE in all color channels, 35% improvement in low-light sensitivity, and 45% increase in full well capacity over the first generation OmniBSI). The dark current of the new sensor is 10e/s at 50C.

The new OV8835 sensor delvers 30fps at full 8MP resolution for zero shutter lag (was 24fps in the older OV8830). The current consumption at that speed is 152mA, the power is 265mW. It is capable of capturing full 1080p30 video with EIS, or 720p60 video with full horizontal FOV. The sensor's 2 x 2 binning functionality with post-binning resampling filter minimizes special artifacts and removes image artifacts around edges.

The OV8835 fits into an industry standard 8.5 x 8.5 mm package. It is currently available for sampling and is expected to enter volume production in the Q4 2012.

PR Newswire: OmniVision introduces the OV5645, a 1.4um BSI pixel-based 5MP SOC that targets the cost-sensitive segment of the mobile handset market. As the successor to a popular OV5640, the new low-cost OV5645 has retained only a MIPI port, eliminating both the bandwidth-limited DVP interface and the costly embedded JPEG compressor. With an embedded AF VCM driver, the OV5645 offers further cost savings for manufacturers.

"Industry analysts predict 5-megapixel image sensors will remain highly popular for mobile devices for the next few years. Consequently, there is an increased need for cost-effective 5-megapixel cameras that meet the requirements of mainstream mobile markets," explained Per Rosdahl, senior product marketing manager at OmniVision. "The OV5645 SOC sensor provides handset manufacturers with a fully-featured yet extremely cost-effective solution that delivers the high-quality image capture and HD video currently required in the mainstream handset market. In addition, the OV5645's increased CRA enables ultra-thin camera modules with z-heights of approximately 4 mm, which is a key requirement for many OEMs' future products."

The OV5645 also features a new picture-in-picture (PIP) based on a master/slave configuration where a secondary camera (e.g., one based on the OV7965) can be connected to a master camera (OV5645).

Update: According to Panasonic Annual Report 2012, its businesses are undergoing a reorganization with the main focus in semiconductors shifting to image sensors and power devices "which continue to exhibit high-growth potential" (see page 12, 33):

Friday, October 26, 2012

Marketwire: Mobileye and ST announce that their jointly developed vision processor SoC, using Mobileye's EyeQ technology, is now deployed in more than one million vehicles around the world. With a growing list of manufacturers building the system into their vehicles, including BMW, GM, Volvo, Ford and many more, ST and Mobileye expect to continue to expand their presence in the automotive safety market.

Developing driver safety technology since 2005, Mobileye and ST have delivered two generations of vision processors that use Mobileye's collision avoidance technology and ST's automotive-grade manufacturing and expertise to 'interpret' a scene in real-time and provide drivers and their vehicles with an immediate evaluation. The third-generation EyeQ3 is in development and will be introduced by car makers as early as 2014.

"The deployment of our millionth device is a major milestone in Mobileye's development and growth, and speaks to the strength of our partnership with STMicroelectronics," said Ziv Aviram, CEO of Mobileye. "More significantly, it exemplifies the growing commitment of global automakers, lawmakers and consumers to making driver safety a top priority, a reality we can all be proud of."

Marketwire: CogniVue unveils its next generation APEX-2 Image Cognition Processing engine that is said to revolutionizes embedded vision technology. The APEX-2 makes significant advances in vision processing performance per area per power over the original APEX (which already had up to a 10x advantage over competitive approaches). CogniVue will be releasing new ICP products based on APEX-2 in 2013 and will also be licensing APEX-2 IP to strategic partners.

"Our ICP products, based on our current APEX technology, are already penetrating a number of markets. We see significant semiconductor vendors struggling with a lack of adequate vision processing IP (chips and software) to complement their existing processor architectures similar to when GPUs were first introduced for graphics processing more than a decade ago." said Simon Morris, CEO of CogniVue Corporation. "By licensing APEX technology to strategic partners like Freescale, we enable new embedded vision roadmaps in different markets, accelerate the propagation of our technology into even more applications, and grow our code base overall. With APEX-2, we have an even higher performance embedded vision processing platform with enhanced flexibility to advance our next-gen ICP product line while also enabling our strategic partners like Freescale."

"Today's collision avoidance systems are typically enabled by digital signal processors or field-programmable gate arrays. Freescale is taking a different approach by integrating CogniVue's Image Cognition Processing IP into our processors, providing massively parallel processing in small packages and with very low power consumption." said Ray Cornyn, VP of Freescale's Automotive MCU Division.

New Imaging Technology (NIT) announces a new global shutter member of its WDR sensor family - the 1.3MP, 140dB NSC1003. It's said to be the first sensor delivering a DR of more than 140dB in a single frame, a resolution of 1.3MP and a global shutter function combined. The sensor is based on 6.8um pixels and has 2/3-inch optical format. The sensor has global and rolling shutter readout modes and provides a differential analog output. The NSC1003 is available for pre-order.

NIT is going to demo the new sensor at the VISION Show 2012 in Stuttgart on Nov. 6-8. NIT also nominated for Vision Award for its MAGIC 3D stereoscopic platform.

Canon debuted its large format CMOS sensor in EOS C300 Digital Cinema Camera in November of 2011 at a global launch event held at Paramount Studios in Hollywood. By exploring alternatives to the established Bayer color filter array algorithms, Canon was able to achieve an overall image quality capture through its CMOS sensor that has helped bring digital cinema closer to the superb aesthetics associated with 35 mm motion picture film.

Over the past 10 months, the company has introduced a total of three high-definition, high-performance Cinema EOS digital cinema cameras—the EOS C300 Digital Cinema Camera, the EOS C500 4K Digital Cinema Camera and the compact, lightweight EOS C100 Digital Video Camera—all built around Canon's Super 35mm CMOS image sensor technology specifically developed for Cinema EOS motion image capture. Separately, the EOS-1D C 4K DSLR Cinema Camera, equipped with an 18.1-megapixel full frame (36 mm x 24 mm) CMOS image sensor, also joined the Cinema EOS product family in April of this year. For professional photographers, and independent and student filmmakers, Canon has also introduced the EOS 5D Mark III digital SLR camera, building on the strong success of the EOS 5D Mark II in film and television production.

ETNews.com reports that SK Hynix announced on Oct. 17 that it recently had succeeded in developing a 8MP BSI prototype. This allows the company to overcome FSI sensors limitations and close gaps with its competitors, according to the ETNews article.

A spokesperson for SK Hynix said it expects the new technology is expected to lead to huge improvements in its market share of the mobile CIS, which currently hovers around 8%, and its profitability. The company aims to apply the BSI technology to a majority of its CIS products by 2014.

Korea Times reports about a partnership between Samsung and Hynix where Hynix supplies sensors for Samsung smartphones and tablets. The newspaper's sources say that SK Hynix has been providing Samsung with 5MP sensors for its lower-end smartphone models. Samsung is said to buy about 45% of the image sensors manufactured by SK Hynix.

It seems that Samsung has already committed to buy BSI sensors from Hynix:

"As cameras in mobile devices have become essential features, we are buying more backside illuminated (BSI) sensors from SK Hynix because they provide good pricing and output commitment," said an unnamed Samsung official Friday, Oct 19. "The resolution in phone cameras has been improving, evidenced by lavish pixel counts. We need to hedge risks across suppliers and we are still buying billions of dollars worth of sensors from Sony. But it’s also true that we are increasing BSI sensor supplies from SK Hynix significantly."

An unnamed Hynix official said about his company's BSI plans: "We are heavily investing to boost our presence in the market for these sensors. From the first quarter of next year, we will be mass producing sensors for eight-mega pixel cameras and from late next year for 13-megapixel cameras."

Hynix' revenue from all its non-memory businesses, including image sensors, is reportedly below 5%.

e2v announces that it has been awarded a £3.8m grant from the Regional Growth Fund administered by the UK Department for Business Innovation and Skills. The grant is part of an overall investment of £13.5m into e2v's space imaging business. It is anticipated that the project will create 130 new jobs at e2v and a further 30 jobs with e2v’s partners over the coming 3 years, including at the Open University and Rutherford Appleton Labs.

This imaging receiver (without antenna) achieves a measured average responsivity and noise equivalent power (NEP) of 285MV/W and 8.1fW/Hz1/2 respectively, across the 86-106GHz bandwidth, which results in a calculated NETD of 0.48K with a 30ms integration time. This represents a 1-2 orders of magnitude improvement in NEP vs. other methods and demonstrations to date, a 4-10x improvement in NETD vs. e.g. 65nm CMOS. With antenna, the system NETD increases to 3K with on-chip antenna due to its low antenna efficiency at W-band. This work demonstrates the highest integration level of any silicon-based system in the 94GHz imaging band and the responsivity achieved is orders of magnitude higher than previous work.

The FPA designed and fabricated using TowerJazz's silicon process incorporates four Dicke-type receivers representing four imaging pixels. Each receiver employs the direct-conversion architecture consisting of an on-chip slot folded dipole antenna, an SPDT switch, a low noise amplifier, a single-balanced mixer, an injection-locked frequency tripler (ILFT), an IF variable gain amplifier, a power detector, an active bandpass filter and a synchronous demodulator. The LO signal is generated by a shared Ka-band PLL and distributed symmetrically to four local ILFTs. The measured LO phase noise is -93dBc/Hz at 1MHz offset from the 96GHz carrier.

Within the millimeter-wave frequency range (30-300GHz), there are propagation windows located near 35, 94, 140, 220GHz, where the atmospheric absorption is relatively low.

Monolithic optical structures for light gathering in image sensors are focused. First, microlens progresses, such as gapless microlens, inner microlens and light pipe are explained. Then, back side illumination (BSI) is compared with front side illumination (FSI). Lastly, recent FSI technology, SmartFSI, is reported along with its pixel shrinkage results.

This presentation is supposed to explain how Panasonic claims on making small FSI pixel better than BSI.

1.12um backside illuminated CMOS image sensor with backside deep trench isolation (DTI) has been demonstrated for the first time. DTI is fabricated on backside surface after wafer bonding and grinding process. Backside DTI makes its layout simple because no transistor isolation exists on backside. We have confirmed 50% reduction of crosstalk.

Many groups have experimented with DTI idea, but the higher dark current and hot pixel rate prevented its productization so far. I wonder whether Toshiba engineers were able to solve these problems.

This work presents a complete and quantitative analysis of the ultra-high extrinsic quantum efficiency in amorphous oxide hetero-TFT image sensors, taking into account the high sub-gap optical absorption due to oxygen vacancies, extended electron lifetime due to retarded recombination, and the reduced transit time associated with short channel lengths.

A graphene stack (GS) structure assembled by layer-by-layer (LBL) transfer of single-layer graphene (SLG) is applied in field effect transistors (FETs) for photodetection. Excellent optoelectronic performance of ~3.6 times increased photocurrent (PC) together with increased internal/external quantum efficiency (IQE/EQE) is obtained in the LBL-GS-FET compared to the conventional SLG-FET, owing to (i) the improved electrical transport, e.g., carrier mobility (4.1 times higher), sheet resistance (61% reduced) and contact resistance (81% reduced) etc., and (ii) the increased optical absorption (over fivefold higher in the visible spectrum). A photovoltaic (PV) model of the LBL-GS-FET was established, indicating a peak of PC generation due to the optimized gate modulation. Both the experimental and theoretical results suggest the LBL-GS as an excellent material for high efficiency optoelectronics.

Hydrogen-plasma-enhanced Se vapor selenization is used to produce efficient Na-free CuInSe2 (CIS) sensor and solar cell, and low temperature plasma-deposited Si thin film solar cell and transistor with 400 cm2/V-s mobility are stacked on top the CIS layer. For the first time, we report a novel stacked Si/CIS/Si solar cell design that provides 15.8%-efficient bifacial operation. The Si TFT and back side Si solar cell is also an effective UV-visible band filter reducing light degradation and environmental noise on CIS image sensor. This hybrid image sensing and energy-harvesting technology is intended for applications in multi-functional panel with CIS performing both stacked solar cell and stacked TFT/sensor functions but in separate areas.

Session 33 on 3D stacking has a paper on 3D-integrated image processor:

We demonstrate the chip-level hetero-integration technology for high speed and highly parallel 3D stacked image processing system. The different function chips, which were fabricated by different technologies, are processed and stacked vertically to form a prototype 3D stacked image processing system in chip-level. The fundamental functions of each layer are characterized in the prototype 3D stacked image processing system.

While not directly related to image sensors, Random Telegraph Noise (RTN) is starting to affect digital circuits in the new highly scaled technologies. Session 19 and 25 discuss it in a number of papers, such as this one:

By measuring 1680 ROs fabricated in a commercial 40 nm CMOS technology, statistical nature of RTN-induced delay fluctuation is described. Small number of samples have a large RTN-induced delay fluctuation. It is found that the impact of RTN-induced delay fluctuation becomes as much as 10.4% of nominal oscillation frequency under low supply voltage (0.65V) operation. It is also found that more than 50% reduction of frequency uncertainty can be achieved under 0.75V operation by slightly increasing the transistor size. The impact of the parameters that can be changed by circuit designer is clarified in view of RTN-induced CMOS logic delay uncertainty.

Seeking Alpha releases some data on Ambarella video ISP business toward its planned NASDAQ IPO. The business is quite dynamic: ISPs for pocket video cameras accounted for 40% of the company's revenue in 2011, went down to 15% in fiscal 2012 and then to only 1% of revenue in the first half of fiscal year 2013. The proliferation of smartphones and their ability to capture high-quality video and still images has effectively wiped out the pocket video cameras market.

The sharp drop of pocket video market has been compensated by rising sales on wearable sports camera market, the IP security camera market and the automotive aftermarket cameras. For the six months ended July 31, 2012, 72% revenue was attributable to the camera market and 28% of revenue was attributable to sales into the infrastructure market.

On the infrastructure market, Ambarella customers include Harmonic, Motorola Mobility (owned by Google), and Telefonaktiebolaget LM Ericsson. On the camera market, Ambarella's chips are designed into products from leading OEMs including GoPro, Robert Bosch and affiliated entities and Samsung, which sources its solutions from ODMs including Ability Enterprise, Asia Optical, Chicony, DXG, Hon Hai, and Sky Light Digital.

As of July 31, 2012, Ambarella had 425 employees worldwide, 81% of whom are in R&D.

Ambarella (AMBA) planned a $60M IPO with a market capitalization of $259M at a price range mid-point of $10 for today, October 10, 2012. However, at the last moment the share price was changed to $6, so that the company IPO raised only $36M. The trade opened at $6.64 and is currently trading at $6.32.

BBC: Microsoft's Digits prototype is part of an effort to bring gesture-based control in a mobile device. A wrist-worn sensor uses IR laser, LEDs and camera to recognize the fingers movement, as shown in Microsoft's paper:

While the prototype is quite big, the company would like to shrink it a size of wrist watch that can be worn all the time. An Youtube video shows Digits sensor in action. A longer version of this video from Microsoft site also offers some insight into the algorithms used for fingers recognition, talks about functions of laser and LEDs and more:

Microsoft's team acknowledged the current device was still some way from being ready for market. It currently needs to be attached to a PC to carry out the necessary computations, making it impractical for real-world use. It also struggles if two fingers are crossed, the hand is flattened or if the user is holding something while making the gestures. However, the researchers suggested all these issues could be overcome with further work.

It looks like SiOnyx gets competition on the black silicon market (so to say, I'm not sure there is a market yet). Fraunhofer announced a progress in its own black silicon manufacturing process.

"Black silicon is produced by irradiating standard silicon with femtosecond laser pulses under a sulfur containing atmosphere," explains Dr. Stefan Kontermann, who heads the Research group "Nanomaterials for Energy Conversion" within the Fraunhofer Project Group for Fiber Optical Sensor Systems at the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut, HHI. "This structures the surface and integrates sulfur atoms into the silicon lattice, making the treated material appear black." If manufacturers were to equip their solar cells with this black silicon, it would significantly boost the cells’ efficiency by enabling them to utilize the full Sun spectrum.

So, the Fraunhofer researchers are planning a spin-off to market the laser system that manufacturers will be able to acquire to expand their existing solar cell production lines. "We hope to be able to increase the efficiency of commercial solar cells – which currently stands at approximately 17 percent – by one percent by combining them with black silicon," Kontermann says.

While Fraunhofer claims are quite similar to ones of SiOnyx, the SiOnyx name has not been mentioned in the article. A year ago SiOnyx reported achieving 0.3% improvement in solar cell efficiency.

TV Week: The National Academy of Television Arts & Sciences (NATAS) announced the recipients of the 64th Annual Technology & Engineering Emmy Awards that will take place at CES on January 10, 2013. This is the 7th consecutive year that the Technology and Engineering Emmy Awards have been presented.

One of the awards go to the imaging companies for "Improvements to Large Format CMOS Imagers for Use in High Definition Broadcast Video Cameras". The companies that get the award are:

Arnold & Richter Cine Technik (ARRI)

Canon USA, Inc.

RED Studios

Sony Electronics Inc.

I was told that the fact that the adjectival phrase "large format" was inserted means that all others are still under consideration for future awards.

Ubergizmo reports that Rohm’s CIGS NIR image sensor won CEATEC Japan 2012 Innovation Award. Rohm's sensor was selected because it allows the creation of NIR cameras that are much more power-efficient, small and cost effective than alternative solutions.

Different version of this sensor have been exhibited at CEATEC shows since 2007 (Tech-On), but have not been awarded up to now.

Wednesday, October 03, 2012

Ubergizmo quotes Japanese-language Egami blog (via Google translation) describing a recently published Sony patent application on a method to create a curved image sensor surface. I was unable to find the original patent application link, so the only available info is what's published by Egami:

According to the Egami post, Sony proposes to control curvature by varying the magnetic force, volumetric shrinkage of the base due to heat, or by changing a vacuum suction force. Sony says that one needs to leave a flat portion of silicon around the curved one to avoid cracks.

Medical image sensor shipments are predicted to grow from 1.8M units to 4.2M units in
